When is the next ocean fishing boat?

How does Artifact deal with board vomit or all the big boards that start coming out after turn 7?
They don't have any bane or board wipes outside the artifact that deals 3 to board or the cannon where it's somewhat hard to find a time to drop that thing. Gotta feed it gears and artifacts too which is fairly hard given that most crafts just vomit big board after big board.

I want to play this but I have no idea how to play it.
